- Figure 6 is a section on line 6-6 Figure 5. Figure 7 is an elevation of the closure plate for a clean-out opening.

A water heater, in accordance with this invention, comprises a body portion referred to generally by the reference character 8 and formed from a single casting. The bodyv portion 8 includes an inner member 9 and an outer member 10 of greater length than the inner member 9, and the latter is suspended from the outer member 10, as well as being spaced therefrom. The inner member 9 preferably is of semi-oval cross section and which forms an inner water heating chamber 11. The innermember 9 includes a top plate 12 which provides the top Wall of the chamber 11. The plate 12 is of greater diameter than the remaining part of the inner member 9 whereby an outwardly directed flange 13 is formed at the top of the member 9. The diameter of the plate 12 is such with respect to the inner diameter of the outer member 10 to provide an endless, narrow opening 14 between the edge of the flange 13 and the inner face of the member 10 at the top thereof. The opening 14 provides an air space or draft between the members 9 and 10 and which is provided to bring The member 10 is in the form of an annulus, which is hollow and provides an outer water heating chamber 15. The member 10 may be termed a water jacket which surrounds the member 9 and the latter is in the form of a bowl. i

Tnterposed between the member 9 and inner wall of the chamber 15, in proximity to the upper ends thereof, is a pair of tubular members 16 which are diametrically dis posed with respect to the members 9 and 10. The member 9 is formed with a pair of diametrically opposed openings 17 and the inner wall of the chamber 15 with a pair of diametrically opposed openings 18. The inner ends of the members 16 are integral with the member 9 and register with the opening 17. The outer ends of the members 16 are integral with the inner wall of the chamber 15 and register with the openings 18. The tubular members 16, in connection with the openings 17 and 13 provide water circulating connections between the chambers 15 and 11. The members 16 further provide means for suspending the inner member 9 within and from the outer member 10.

Arranged between the members 9 and 10, in proximity'to the bottoms thereof, is a tubular member 19 which inclines downwardly from the member 9 to the member 10. The member 9 is formed with an opening 20 and the inner wall of the chamber 15 with an opening 21. The tubular member 19 is formed integral with the members 9 and 10 and register with the openings20, 21. The member 19 provides a clean-out connection for the chamber 11 and also assists in suspending the member 9 from the member 10. v

The outer wall of the chamber 15 is formed with a pair of diametrically opposed circumferentially extending; slots 23, 24, of substantial width and length and which provide clean-out openings for the chamber 15. The slot 24 opposes the opening 21 formed in the inner wall of the chamber15. The slots 23, 24 are of rectangular contour and secured to the outer face of the outer wall of the chamber 15 and surrounding each of said slots is a rectangular frame 25 conforming in curvature to the curvature of the outer member 10. Each frame has anchored thereto and projecting outwardly therefrom a series of peripherally threaded meniibers 26. Positioned. against each frame 25, as well as connected thereto, in a manner to be presently referred to, is a 010 sure plate 27 which conforms in curvature to the curvature of the member 10. The plate 2? as best shown in Figure 7, is of rectangular contour and formed with openings 28 in proximity to its top and bottom edges thereof and is further formed at each end with a pair of slots 29. The openings 28 and 29 are provided for the passage of the threaded members 26 and mounted on these latter are clamping nuts 30. which fixedly secure the plate 27 against the frame 25 thereby closing a slot 23 or 24. To provide for a watertight joint, a packing 31 is interposed between the plate 27 and the frame 25.

The top plate, forming a part of the inner member 9, is formed with an opening 32 and integral with the upper face of the plate 12, is a vertically disposed interiorly threaded collar 33, having its inner diameter. greater than the inner diameter of the opening 32 whereby the threaded inner face of the collar 33 will be spaced from the opening 32, and an abutment or shoulder 34 will be formed at the inner end of the collar Threadably engaging with the collar 33 is a hot Water or steam outlet pipe 35.

The plate 12 is furthermore provided with.

an opening 36 of greater diameter than the opening 32 and spaced a substantial distancetherefrom, but in alignment therewith. Formed integralwith the upper face of the plate 12 is a collar 37 of greater diameter than the collar 32 and which registers with the opening 36. The wall of the opening 36 is threaded, as well as the inner face of the collar 37 and engaging with said threads is a removable clean-out plug 38.

The outer wall of the chamber 15 is pro- I vided'with an opening 39, which opposes the opening-18 and said outer wall of said chamber 15 has formed integral with its outer face an interiorly threaded collar 40 which surrounds the opening 39 and the inner diameter of the collar 40 is greater than the diameter of the opening 39 thereby providing a shoulder or abutment 41. Threadably engaging with the collar 41 is hot water outlet pipe 42. The inner end of the pipe 35 is positioned against the shoulder or abutment 34 and the inner end of the. pipe 42 is positioned againstthe shoulder or abutment 41. The pipe 35 provides a hot water or steam outlet for the chamber 11 and the pipe 42 provides a hot wateror steam outlet for the chamber 15. The pipes 35 and 42 are disposed at right an les with respect to each other.

The outer wall of the chamber 15, is provided with an opening 43 which is arranged below the opening 39 and formed integral or steam The pipe 46' boiler in proximity to the bottom thereof. The pipe 42 communicates with the water or steam boiler at a level a substantial distance above the point of communication of the pipe 46 with the water or steam boiler and the pipe 35 communicates with the water or steam boiler at a level a substantial distance above the point of communication between the pipe42 and the water or steam boiler. I

The outer member 10 has formed with its bottom, at diametrically opposed points, a pair of depending short arms 47, to which is connected a pair of suspension members 48 for a valve controlled gas supply pipe 49 which extends through a block 50. The members 48 are fixedly secured to the block 50. The pipe 49 extends a substantial distance above the block 50 and carries a burner element 51 and which is disposed in alignment with respect to the axis of the body portion 8.

The water heater when coupled up to a water or steam boiler expedites the heating of water as well as the generating of steam, particularly in view of the fact that the water heater includes a pair of water heating chambersdisposed to have large heating surfaces or areas for the flame from the burner and the space formed between the inner and outer members of the body portion forms a heating space 52 disposed in a manner'whereby the water heating chambers will be thoroughly heated, and the draft provided by the opening ltwill assist in providing for the flame to attack the inner member 9 and inner face of the outer member lO thereby rapidly heating the water Within the water chambers, and under such conditions it is thought the many advantages of a water heater, in accordance with this invention can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed. w i
